Bihar Student AI Innovation: Rudrachandra Mishra is a Class 10 student from Nahar Chowk in Sitamarhi, Bihar, who developed an AI model designed to identify changes in plant health before visible disease symptoms appear. The idea emerged after he saw a diseased tree during a district-level Children’s Science Congress. He started working on the model in 2024 under the guidance of science teacher Naval Kishore.
The model uses sensors to monitor soil moisture, temperature and plant conditions while also assessing the plant’s water and nutrient requirements. Rudra presented the model online at InnoRobo by SIDO 2026 in Lyon, France, on September 16 and 17 and secured 37th place among 1,472 students from 87 countries.
AI Model Can Detect Plant Health Before Visible Symptoms
Rudrachandra’s model continuously monitors the condition of plants and soil moisture. Its primary objective is to identify changes in a plant before clear signs of disease become visible. The system can also indicate when the plant needs water or specific nutrients.
The model has been designed with an additional mechanism that can supply the required quantity of water from a tank when the plant needs irrigation. This makes the innovation potentially useful for monitoring plant requirements and managing water use.
Who Guided Rudrachandra Mishra?
Rudra began working on the model in 2024 after getting the idea from a diseased tree during the district-level Children’s Science Congress. His science teacher, Naval Kishore, guided him during the experiments.
The source states that Rudra developed his basic knowledge of electronics and technology through the internet during the lockdown period. He then continued experimenting and gradually developed the model. After presentations at the district and state levels, the project was selected for the national level. Around 400 students from across India were selected, including 14 students from Bihar.
Sensors nd Camera Used to Monitor Plants
The AI model incorporates eight microcontrollers, different sensors, an air module, soil-moisture sensors and a camera system. The information collected through these components is used to understand the condition of the plant and soil.
According to the source, developing the model currently costs around Rs 29,000 to Rs 45,000. Rudra is also working to reduce the cost. A smaller version of the model could be developed for approximately Rs 10,000 to Rs 15,000.
Rudrachandra Mishra’s Model Could Help Farmers
Rudra now wants to further develop his innovation. One of his goals is to make the model capable of helping farmers select suitable crops based on available water during periods of low rainfall or water scarcity.
The model could potentially help farmers understand irrigation requirements and use available water more efficiently. The initiative has also received appreciation from Sacred Heart School Director Christopher Raj, who said Rudra had transformed his curiosity into a useful experiment and brought recognition to the school at the international level.
From a Diseased Tree to International Recognition
Rudra’s parents, advocate Ritesh Kumar and Mousami Mishra, said that the family also supported him while developing the model. What began with a question after seeing a diseased tree eventually became an innovation presented on an international platform.
The achievement has been described as a matter of pride for Sitamarhi. District Education Officer Raghavendra Mani Tripathi said such talented students should receive support and highlighted the role of the Children’s Science Congress in encouraging students to experiment and develop their ideas.
